Compared with the existing EPS, the wireless communication system comprising the wireless access network provided by the embodiment of the invention realizes a flat network architecture, deletes the core network functional entities such as PDN-GW, S-GW, PCRF and MME in the existing EPS, and the network side entity can only comprise the wireless access network and a second server; the access network may include: an access node and a control plane anchor. The control plane anchor point can integrate the functions of network function entities such as eNB, MME and the like in the EPS shown in fig. 1, thereby implementing the flattening of the network of the whole wireless communication system.

By adopting the flat network architecture, the problem that communication links from eNB to MME, from MME to HSS and from MME to service gateway become the bottleneck of processing capacity of a wireless communication system is avoided, the signaling transmission delay is effectively reduced, and the network paralysis risk is reduced.

When the wireless connection control method is applied to a scene that a control plane anchor point and a user plane anchor point are separated, the aims of centralized control and service data distribution can be achieved.

In another aspect, embodiments of the present invention provide a method for processing an IP packet, a server, and a device in a radio access network, so as to avoid a complex QoS management process in the current LTE system, and replace core network devices such as PCRF, PDN GW, and MME in the current LTE system with a user plane anchor point or a control plane anchor point, thereby simply implementing QoS management.

the radio access network 202 is wirelessly connected to the terminal 201 through an air interface (air interface) such as a Uu interface, so as to implement network access of the terminal 201.

The wireless connection may also be referred to as an air interface connection, and the terminal has a wireless connection with a base station or an access node in a radio access network, and may communicate with the base station through the wireless connection.

Second, wireless communication system

Different wireless communication systems can adopt different wireless communication modes, and the wireless communication modes suitable for the embodiment of the invention include but are not limited to the following various modes:

GSM, IS-95, CDMA 2000, TD-SCDMA, WCDMA, TDD, FDD, Long Term Evolution-enhanced (Long Term Evolution-Advance, LTE-compatible), WiFi 802, GSM-GSM, WiFi 802, CDMA-11, WiMAX), bluetooth (Blue Tooth), and the like.

The embodiments of the present invention are directed to providing a flat network architecture, and those skilled in the art will recognize that the network architecture is not only applicable to various possible wireless communication systems, but also applicable to various communication systems of future wireless communication systems.

Third, the base station

The base station is positioned in a wireless access network in a wireless communication system, and the base station is communicated with the terminal through an air interface to realize the access of the terminal to the network.

Fourth, terminal

The terminal may be a user equipment including, but not limited to: mobile phones, tablet computers, Personal Digital Assistants (PDAs), Point of sale (POS), in-vehicle computers, and the like.

Such as: for the LTE systems such as TDD LTE, FDD LTE, or LTE-a, the base station may be an evolved NodeB (eNodeB), and the terminal may be a UE; for a TD-SCDMA system or a WCDMA system, a base station may include: node b (NodeB), or NodeB and Radio Network Controller (RNC), and the terminal may be UE; for a GSM system; the Base Station may include a Base Transceiver Station (BTS), or include a BTS and a Base Station Controller (BSC), and the terminal is a Mobile Station (MS); for a WiFi system, the base station may include: an Access Point (AP) and/or an Access Controller (AC), and a terminal may be a STAtion (STA).

Fifth, the first server

The first server is used for providing application services to the terminals under the coverage of the radio access network, such as: the application server provides service for the user corresponding to the terminal, and the terminal receives service data from the application server or sends the service data to the application server.

Sixth, the second server

Seven, access node

The access node is in wireless connection with at least one terminal in the wireless access network, and communication between the terminal and the first server is realized through the wireless connection between the access node and the terminal.

The access node may be a base station in a cellular wireless communication system (for example, different from a WiFi system), and may include a macro base station, a small station, or even a light small station that only implements part of air interface functions; or may be a node in other WiFi systems such as a WiFi AP.

The small station may refer to a base station with a small communication coverage area and a small maximum transmittable power, such as: a Small Cell (Small Cell), a Pico Cell (Pico Cell), a Home evolved base station (Home eNodeB), a Home base station (Home NodeB), a femto, and the like. Compared with macro base stations, the small station has the advantages of small power, small size, easiness in deployment and the like, and can be flexibly deployed on lamp posts, advertising boards and indoors.

The communication coverage radius of the small station is usually smaller than a preset threshold, such as: 100m, the maximum transmittable power is generally less than a preset power threshold, such as: 10 w.

A lightweight cell may refer to a base station that does not implement a complete air interface protocol stack, such as: taking an LTE system as an example, a base station that only implements PHY, MAC, and RLC layers in an LTE air interface protocol stack and does not implement PDCP and RRC layers may be referred to as a light-weight small station.

The small station and the light small station are different in that the small station realizes a complete air interface protocol stack, and the light small station only realizes a part of air interface protocol stack.

[ Wireless Access network ]

Referring to fig. 3, a radio access network 30 according to an embodiment of the present invention is connected to a first server 31 and a second server 32, where the radio access network 30 may include:

at least one access node 301, the at least one access node 301 having a wireless connection with at least one terminal 33 under the coverage of the radio access network 30 for enabling communication between the at least one terminal 33 and the first server 31 through the wireless connection with the at least one terminal 33;

a control plane anchor 302 connected to the at least one access node 301, the control plane anchor 302 configured to:

controlling a terminal under the coverage of the radio access network 30 to establish a radio connection with one or more access nodes 301 of the at least one access node 301; and

through information interaction with the second server 32, user information management of the second server 32 for the terminal 33 having a wireless connection with at least one access node 301 is achieved.

Optionally, if the wireless communication system is LTE, the control plane anchor 302 may integrate necessary functions of an eNB, an MME, and the like in the current LTE system; if the wireless communication system is WCDMA or TD-SCDMA, the control plane anchor point 302 may integrate the necessary functions of RNC and Mobile Switching Center Server (MSC Server) in the current WCDMA system or TD-SCDMA system. The flattening of the network of the entire wireless communication system is achieved.

Avoiding problems such as: the communication link between the network entity of the radio access network such as the eNB or the RNC and the MME becomes the processing capacity bottleneck of the radio communication system, thereby effectively reducing the signaling transmission delay. Due to the control of the control plane anchor point 302 on the plurality of access nodes 301, the access nodes 301 can be managed through the control plane anchor point 302 during network management, thereby realizing hierarchical management of the network and simplifying network management. And since the terminal 33 moves between different access nodes 301 under the same control plane anchor 302, since the RRC connection anchor of the terminal 33 is at the control plane anchor. Under the same control plane anchor point, the terminal uses the same RRC connection configuration parameters, such as C-RNTI and the like, and does not need to be replaced when the access node is replaced.

The cell switching process is not involved, so that frequent switching of the terminal 33 is avoided, and the call drop rate is reduced.

Alternatively, the control plane anchor 302 may configure the transmission parameters of the established wireless connection when the control terminal 33 establishes the wireless connection with the access node 301.

Such as: the Control plane anchor 302 may configure which Access node 301 the terminal 33 accesses to the Radio Access network 30, and the transmission parameters of layer 1 (e.g., physical layer), layer 2 (e.g., Medium Access Control (MAC) layer, Radio Link Control (RLC) layer) of the Access node 301 to which the terminal 33 is connected, where the configurable parameters include, but are not limited to, at least one of the following parameters:

Maximum transmission times of a hybrid Automatic Repeat reQuest (HARQ);

discontinuous Reception (DRX) cycle;

a maximum transmission bit rate;

maximum uplink transmission power;

parameters of Radio bearers (Radio Bearer);

RB scheduling priority, etc.

Optionally, the control plane anchor point 302 may also be used to perform at least one of the following operations:

performing radio resource control on the terminal 33 to which the terminal is connected;

performing NAS control on the terminal 33 connected to itself;

and performing wireless resource management on the wireless resources managed by the wireless resource management device.

Optionally, the radio access network 30 may further comprise a user plane anchor 303 connected to one or more access nodes 301;

the user plane anchor 303 is used to:

sending the service data forwarded by the one or more access nodes 301 from the terminal 33 wirelessly connected to the one or more access nodes 301 to the first server 31; and

traffic data received from the first server 31 and sent to a terminal 33 having a wireless connection with one or more access nodes 301 is sent to the terminal 33 via the access node 301 to which the terminal 33 is connected.

When the radio access network 30 comprises a user plane anchor 303, the control plane anchor 302 is further operable to: the transmission parameters used when the user plane anchor 303 and the terminal 33 transmit the traffic data are configured.

Optionally, when the user plane anchor 303 is present, the access node 301 may further be configured to:

the service data of the terminal 33 having wireless connection with itself is transmitted to the first server 31 through the user plane anchor 303 connected with itself, and the service data transmitted to the terminal 33 having wireless connection with itself, which is forwarded from the first server 31 by the user plane anchor 303 connected with itself, is transmitted to the terminal 33.

Optionally, the radio access network, the first server and the second server are connected through the internet; different user plane anchor points occupy different network segments of IP addresses. Optionally, when the first server 31 and the second server 32 communicate with the terminal 33, the data of the terminal 33 is sent to the corresponding user plane anchor point through the routing protocol according to the network segment to which the public network IP address of the terminal 33 belongs, and then sent to the terminal 33 by the user plane anchor point.

The user plane anchor 303 may also be used to perform at least one of the following operations:

allocating an IP address to the terminal 33 connected to itself;

converging service data of the terminal 33 connected with the terminal;

filtering is performed for the service data of the terminal 33 connected to itself, such as: packet filtering;

The traffic data for the terminal 33 connected to itself is routed.

Depending on whether or not the user plane anchor 303 is present, and whether or not the control plane anchor 302 and the user plane anchor 303 are located in the same device when the user plane anchor 303 is present, the network architecture of the radio access network 30 may include, but is not limited to, the following three forms:

form one

The control plane anchor 302 and the user plane anchor 303 are located in the same device.

Such as: when the access Node 301 is a Small station, the same device may be a macro base station (as shown in fig. 4A) or a Small Node Controller (SNC) (as shown in fig. 4D), which may be an SDRAN Controller as described above.

Form two

The control plane anchor 302 and the user plane anchor 303 are located in different devices, in which case the control plane anchor 302 is connected with the user plane anchor 303.

When the control plane anchor 302 and the user plane anchor 303 are located in different devices, the access node 301 may be a small station, the control plane anchor 302 may be located in a macro base station (as shown in fig. 4B) or SNC (as shown in fig. 4E), and the user plane anchor 303 may be located in LGW or UGW.

Form III

There is no user plane anchor 303.

At this time, the access node 301 may be a small station, and the control plane anchor point 302 may be located in a macro base station (as shown in fig. 4C) or a small station controller (as shown in fig. 4F);

At this point, the access node 301 may also be configured to: service data of the terminal 33 having a wireless connection with itself is sent to the first server 31, and service data received from the first server 31 and sent to the terminal 33 having a wireless connection with itself is sent to the terminal 33.

Fig. 4A to 4F are six network deployment scenarios of the radio access network according to the embodiment of the present invention, where the scenarios are provided

In the network deployment scenario shown in fig. 4A, the macro base station is a unified user plane anchor point and control plane anchor point;

in the network deployment scenario illustrated in fig. 4B, the macro base station provides coverage, the control plane anchor point is located in the macro base station, and the user plane anchor point is located in the LGW;

fig. 4C shows a network deployment scenario in which a control plane anchor point is located in a macro base station, and no user plane anchor point is provided;

fig. 4D illustrates a network deployment scenario in which the SNCs are unified user plane anchors and control plane anchors;

fig. 4E shows a network deployment scenario in which there is no macro base station coverage, and a user plane anchor point and a control plane anchor point are located in different devices, the control plane anchor point is located in the SNC, and the user plane anchor point is located in the LGW;

fig. 4F shows a network deployment scenario in which there is no user plane anchor point, and the control plane anchor point is located in the SNC.

The above scenario has no user plane anchor 303 or control plane anchor 302, seen from the point of view of the access node 301, but not the terminal 33. There is a user plane anchor 303 indicating that data from multiple access nodes 301 can only enter the internet through this user plane anchor 303.

In addition, a network deployment scenario is also used, as shown in fig. 4G. The network deployment scenario is suitable for a deployment scenario in which the access node 301 is a weakly-managed plug-and-play small station, information does not need to be exchanged between base stations, and the deployment scenario is similar to WiFi fat AP deployment.

Corresponding to the above seven network deployment scenarios, there are seven network function architectures as follows. In each network function architecture, the specific functions between the access node 301 and the user plane anchor 303 and/or the control plane anchor 302 are only used as references, and in actual implementation, the functions can be deleted and/or adjusted according to principles such as function simplification or optimization and the like to be deployed between the access node 301 and two layers of nodes including the user plane anchor 303 and the control plane anchor 302.

Network function architecture one

As shown in fig. 5A, the network functional architecture corresponds to the network deployment scenario shown in fig. 4A.

Local RRM (Local RRM) is used to perform Local resource management, such as: configuring Sonar Reference Signal (SRS) resources and the like for different users.

Joint RRM (Co-RRM) for coordinating radio resource management among access nodes 301 managed by control plane anchor 302, such as: which frequency resource or resources etc. are used by each access node 301 to avoid resource collision or signal interference between access nodes 301.

Dynamic Resource Allocation (Dynamic Resource Allocation) is used to schedule radio resources in each subframe, and allocate the radio resources in the subframe to one or more terminals 33 for use. The radio resource allocation results may be different for different subframes.

Optionally, in order to further simplify the control plane protocol, a separate NAS protocol function may also be deleted, and the necessary functions of the NAS may be incorporated into the RRC protocol.

And terminal IP address allocation (UE IP address allocation) is arranged in the macro base station to reduce data transmission delay, so that the PDN-GW is prevented from becoming a transmission bottleneck of a user plane, the macro base station can be used as an access of a wireless access network connected to the Internet, and the macro base station allocates the terminal IP address.

Packet filtering (Packet filtering) is used for classifying the IP packets from the internet to map the packets to different air interface bearers for transmission, so as to implement QoS differential service.

And a Data routing (Data routing) for routing the IP packet destined to the Internet to the corresponding next-hop router according to the destination IP address.

Multipath TCP/UDP/RTP, etc. (Multi-path TCP/UDP/RTP/… …) for realizing simultaneous transmission of data of the same service by multiple paths.

By adopting the network function architecture I, the existing macro base station can be fully utilized as a user plane anchor point and a control plane anchor point, so that the control of an operator is facilitated, the data transmission delay is reduced, and the PDN-GW is prevented from becoming a bottleneck of user plane transmission.

Network function architecture two

Fig. 5B shows a second network functional architecture, which corresponds to the network deployment scenario shown in fig. 4B. The functions of local RRM, joint RRM, dynamic resource allocation, NAS, terminal IP address allocation, packet filtering, data routing, multipath TCP/UDP/RTP, etc. may refer to the network function architecture one, and are not described herein again.

Optionally, in the second network function architecture, when the macro base station communicates with the terminal in the light cell site, the RRC message may be forwarded and processed by a Universal Gateway (UGW), and at this time, the macro base station may not use its PDCP/RLC/MAC and PHY for processing; and when the macro base station communicates with the terminal which directly communicates with the macro base station, the RRC message needs to be processed by the PDCP/RLC/MAC and PHY of the macro base station.

Optionally, UGW may also be implemented in the small station, which then acts as the user plane anchor point for the lightweight small station in fig. 5B.

Network function architecture III

Fig. 5C shows a network functional architecture three, which corresponds to the network deployment scenario shown in fig. 4C. The functions of local RRM, joint RRM, dynamic resource allocation, NAS, terminal IP address allocation, packet filtering, data routing, multipath TCP/UDP/RTP, etc. may refer to the network function architecture one, and are not described herein again.

In fig. 5C, terminal IP address assignment, packet filtering, and data routing in the macro base station are provided by the macro base station for the terminals served by the macro base station; the terminal connected to the light small station with the macro base station as the control plane anchor point in fig. 5C uses terminal IP address allocation, packet filtering and data routing provided by the light small station.

And meanwhile, through distributed UGW, the user plane anchor point is close to an access node as much as possible, so that the data transmission delay is reduced, and PDN-GW is prevented from becoming a bottleneck of user plane transmission.

Network function architecture four

The network functional architecture four is shown in fig. 5D, which corresponds to the network deployment scenario shown in fig. 4D. The functions of local RRM, joint RRM, dynamic resource allocation, NAS, terminal IP address allocation, packet filtering, data routing, multipath TCP/UDP/RTP, etc. may refer to the network function architecture one, and are not described herein again.

Optionally, data retransmission and ordering can be performed by the PDCP layer, in which case the RLC layer is no longer needed.

And by adopting the network function architecture IV, a plurality of access nodes can be controlled by the SNC and can be used as an access port for entering the Internet in an area without coverage of a macro base station, so that an operator can control and improve the use efficiency of wireless resources conveniently, and meanwhile, the data transmission delay is reduced and the PDN-GW is prevented from becoming a bottleneck of user plane transmission.

Network function architecture five

Network functional architecture five is shown in fig. 5E, corresponding to the network deployment scenario shown in fig. 4E. The functions of local RRM, joint RRM, dynamic resource allocation, NAS, RLC, terminal IP address allocation, packet filtering, data routing, multipath TCP/UDP/RTP, etc. may refer to the network function architecture four, and are not described herein again.

Alternatively, UGW may also be implemented in a small station, which then acts as the user plane anchor point for the lightweight small station in fig. 5B.

And meanwhile, through distributed UGW, a user plane anchor point is close to the access node as much as possible, so that the data transmission delay is reduced and the PDN-GW is prevented from becoming a bottleneck of user plane transmission.

Network function architecture six

Fig. 5F shows a network functional architecture, which corresponds to the network deployment scenario shown in fig. 4F. The functions of local RRM, joint RRM, dynamic resource allocation, NAS, RLC, terminal IP address allocation, packet filtering, data routing, multipath TCP/UDP/RTP, etc. may refer to the network functional architecture four, and are not described herein again.

And in addition, the small station is directly accessed to the internet, so that the data transmission delay can be reduced and the PDN-GW is prevented from becoming a bottleneck of user plane transmission.

In the network function architecture one to the network function architecture six, the RRC may be at an access node, for example: the small station implementation can also be implemented at the control plane anchor point, such as: and (4) realizing macro base station and SNC.

Network function architecture seven

Network functional architecture seven is shown in fig. 5G, corresponding to the network deployment scenario shown in fig. 4G. The functions of local RRM, joint RRM, dynamic resource allocation, NAS, terminal IP address allocation, packet filtering, data routing, multipath TCP/UDP/RTP, etc. may refer to the network function architecture one, and are not described herein again.

And by adopting a network function architecture seven, the small stations can be used as nodes for data transmission and control, so that the control of an operator is facilitated, the data transmission delay is reduced, and the PDN-GW is prevented from becoming a bottleneck of user plane transmission.

From the terminal perspective, all the functional architectures can coexist with the wireless communication system adopting different wireless communication systems and can coexist with the existing wireless communication system adopting different wireless communication systems. All the functional architectures are suitable for small stations capable of working independently, namely standby small stations, and scenes adopting wireless backhaul (relay) among the small stations.

In summary, when the radio access network 30 provided by the embodiment of the present invention includes the access node 301 and the access anchor, and the access anchor includes the user plane anchor 303 and the control plane anchor 302, the network function architecture of the entire wireless communication system may be as shown in fig. 6. Wherein the terminal 33 may access the radio access network via a plurality of access nodes 301.

and the user plane anchor 303 connected to the access node 301 performs processing of the second part of air interface protocol stack on the received uplink data.

For another example: for downlink data, the downlink data may be from the internet or the control plane anchor 302, and the access node 301 and the user plane anchor 303 connected to the access node 301 may perform the following processes:

As mentioned above, when the user plane anchor 303 and the control plane anchor 302 are located in different devices, there may be a plurality of implementations, such as: as shown in fig. 4B, the control plane anchor 302 is located in the macro base station and the user plane anchor 303 is located in the UGW; alternatively, as shown in fig. 4E, the user plane anchor 303 is located in the UGW and the control plane anchor 302 is located in the SNC. When the data processing scheme is applied to the network function architecture shown in fig. 6, the data processing scheme is applicable to both the network deployment scenario shown in fig. 4B and the network deployment scenario shown in fig. 4E.

As mentioned above, the RRC processing can be implemented at the access node 301, and can also be implemented at the control plane anchor 302, which is described here by way of example (as shown in fig. 7) for the RRC processing at the control plane anchor 302.

Fig. 7 shows a typical network functional architecture with a separation of control plane anchor and user plane anchor. The control anchor 302 implements RRC, NAS and RRM functions that require cross-station coordination; the access node 301 implements RRM, dynamic resource allocation function and part of air interface user plane protocol (for example, PHY layer, MAC layer and RLC layer) closely related to layer 1 and layer 2 local configuration of the terminal; and the user plane anchor point 303 implements other protocols (such as PDCP) of the air interface user plane, and the terminal IP address allocation, packet filtering and data routing functions implemented by the original PDN-GW.

The division point of the air interface protocol stack between the user plane anchor point 303 and the access node 301 may also be below the RLC layer or the MAC layer, and the present solution uses the PDCP layer as the division point. In addition, the scheme is also suitable for the condition that the empty interface user plane protocol stack does not strictly contain a PDCP layer, an RLC layer, an MAC layer and a PHY layer, such as: the same applies to the case where there is no RLC layer in the air interface protocol stack.

It should be noted that the data processed by the data processing scheme provided by the embodiment of the present invention may include service data and control messages.

Next, a data processing scheme provided in an embodiment of the present invention is described by taking an RRC connection establishment procedure shown in fig. 8 as an example. The scheme is also applicable to other RRC procedures, such as: the RRC connection release procedure, RRC connection reconfiguration, and other procedures have the same principle, and are not described herein again.

Referring to fig. 8, the RRC connection establishment procedure includes the steps of:

s801: the terminal 33 initiates a random access procedure to the access node 301;

the terminal 33 initiates or autonomously initiates a random access process to a certain cell under the access node 301 under the instruction of the radio access network 30, so as to realize uplink and downlink synchronization with the cell and obtain the C-RNTI.

Wherein, the terminal 33 may send a random access preamble (preamble) to the access node 301, the access node 301 sends the accessed random access preamble to the control plane anchor point 302, the control plane anchor point 302 processes the random access preamble, the processing mode may be the same as that in the current LTE system, and allocates a user identifier for the terminal 33, for example: a Cell-Radio Network Temporary Identifier (C-RNTI) is forwarded to the terminal 33 through the access node 301, for example: and is sent to the terminal 33 by means of a random access response.

S802: the terminal 33 sends an RRC Connection Request (RRC Connection Request) to the access node 301, requesting establishment of an RRC Connection;

After receiving the RRC connection, the access node 301 performs PHY/MAC/RLC processing, and then sends the processed result to the user plane anchor 303; the user plane anchor 303 further performs PDCP processing, and then sends the PDCP processed message to the control plane anchor 302, where the control plane anchor 302 performs RRC processing, analyzes the RRC message, and determines whether an RRC connection can be established for the terminal 33, and the determining method may refer to implementation in the current LTE system, and is not described herein again.

The processing of the RRC message by the access node 301, the user plane anchor 303, and the control plane anchor 302 may constitute the processing of the complete air interface protocol stack of the radio access network.

In the flow shown in fig. 8, the access node 301 performs PHY/MAC/RLC processing, and the user plane anchor 303 performs PDCP processing, for example, but the actual segmentation of the air interface protocol stack is not limited to this, for example: the access node 301 performs PHY/MAC processing, and the user plane anchor point 303 performs RLC/PDCP processing; or, the access node 301 performs PHY processing, and the user plane anchor 303 performs MAC/RLC/PDCP processing.

S803: the control plane anchor 302, after determining that it is possible to establish an RRC Connection for the terminal 33, generates an RRC Connection Setup (RRC Connection Setup) message, which typically contains radio resource configuration information, and sends the message to the user plane anchor 303; the user plane anchor 303 performs PDCP processing on the message, and then sends the processed message to the user plane anchor 303 for PHY/MAC/RLC processing, and the access node 301 sends the processed message to the terminal 33.

S804: the terminal 33 transmits an RRC Connection Complete (RRC Connection Complete) message to the access node 301;

similar to step S804, the message performs PHY/MAC/RLC processing at the access node 301, PDCP processing at the user plane anchor 303, and RRC processing at the control plane anchor 302, respectively, in the order "terminal 33-access node 301-user plane anchor 303-control plane anchor 302". The message typically contains mobile network operator identification information selected by the terminal.

S805: after receiving the RRC connection complete message, the control plane anchor 302 may send configuration parameters of the PDCP to the user plane anchor 303, such as: a security key; transmitting configuration parameters of PHY/MAC/RLC to access node 301;

as mentioned above, the segmentation of the air interface protocol stack may include, but is not limited to, the following segmentation modes:

the access node 301 performs PHY/MAC/RLC processing, and the user plane anchor 303 performs PDCP processing; or the access node 301 performs PHY/MAC processing, and the user plane anchor 303 performs RLC/PDCP processing; or the access node 301 performs PHY processing, and the user plane anchor 303 performs MAC/RLC/PDCP processing.

Regardless of the partition manner, the control plane anchor 302 configures an air interface protocol stack of the user plane anchor 303 and an air interface protocol stack of the access node 301, respectively.

The configuration parameter is configured for the terminal 33, such as configuring a Radio Bearer (RB) of the terminal 33, for example: signaling Radio Bearer (SRB), which may be used to carry RRC messages and/or NAS messages, such as: a Dedicated Radio Bearer (DRB), which may be used to carry service data of the terminal 33.

The user plane anchor 303 and the access node 301 configure an air interface protocol stack according to the received configuration parameters, and process the subsequent received RRC message and/or service data by using the configured air interface protocol stack.

Optionally, the access node 301 and the user plane anchor 303 may use default parameters for processing the RRC message before the control plane anchor 302 sends the configuration parameters.

S806: the control plane anchor 302 sends a Security Mode Command (Security Mode Command) message to the terminal 33;

the message mainly contains security related parameters such as: parameters of the integrity protection algorithm, etc. The message is sent to the terminal 33 along the sequence of the control plane anchor 302, the user plane anchor 303, the access node 301, and the terminal 33, where the user plane anchor 303 and the access node 301 respectively perform processing of respective air interface protocol stacks, and the processing manner is similar to that in step S803, and is not described herein again.

Step S805 and step S806 have no strict order relationship; alternatively, the messages of the two steps S805 and S806 may be packaged by the control plane anchor 302 and sent in one large message.

S807: terminal 33 sends a Security Mode Complete message to access node 301;

s808: the control plane anchor 302 transmits an RRC Connection Reconfiguration (RRC Connection Reconfiguration) message to the terminal 33;

this message is mainly used for dedicated bearer configuration and/or measurement configuration, etc., and is ultimately delivered to the terminal 33.

S809: the terminal 33 transmits an RRC Connection Reconfiguration Complete (RRC Connection Reconfiguration Complete) message to the access node 301;

the terminal sends the message to the access node 301 after configuring the dedicated bearer and/or measurements etc.

In the above steps S807 and S809, the message is finally submitted to the control plane anchor 302 along the sequence of "terminal 33-access node 301-user plane anchor 303-control plane anchor 302", where the access node 301, the user plane anchor 303 and the control plane anchor 302 respectively perform processing of respective air interface protocol stacks, and the processing manner is similar to that in step S802, and is not described herein again.

In step S809, the message is finally sent to the terminal 33 along the sequence of "control plane anchor 302-user plane anchor 303-access node 301-terminal 33", where the access node 301, the user plane anchor 303, and the control plane anchor 302 respectively perform processing of respective air interface protocol stacks, and the processing manner is similar to that in step S803, and is not described again here.

In the RRC connection establishment procedure, the terminal 33 sends a message to the control plane anchor 302, such as: RRC connection request, RRC connection completion, security mode completion, and RRC connection reconfiguration completion, which may be collectively referred to as "a first control message" in the embodiments of the present invention;

the control plane anchor 302 sends messages to the terminal 33, such as: RRC connection establishment, security mode command, RRC connection reconfiguration, which may be collectively referred to as "second control message" in the embodiments of the present invention.

As described above, the data processing scheme provided in the embodiment of the present invention is not only applicable to the radio connection establishment procedure, but also applicable to other procedures, such as radio connection release, radio connection reconfiguration, and the like, so that the terminal 33 in these procedures sends a message, which is used to control the radio connection of the terminal 33 in the radio access network 30 and is sent to the control plane anchor 302, and may also be referred to as a "first control message"; similarly, the message sent by the control plane anchor 302 to the terminal 33 for controlling the wireless connection of the terminal 33 in the radio access network 30 in these procedures may also be referred to as a "second control message".

Taking RRC message as an example, the first control message may further include, but is not limited to, the following messages:

an RRC Connection Reestablishment Request (RRC Connection Request) message;

RRC Connection Reestablishment Complete (RRC Connection request Complete) message.

Taking RRC message as an example, the second control message may further include but is not limited to the following messages:

an RRC Connection Reestablishment (RRC Connection request) message;

an RRC Connection Reject (RRC Connection Reject) message;

an RRC Connection Reestablishment Reject (RRC Connection rejection Reject) message;

RRC Connection Release (RRC Connection Release) message.

In the data processing scheme provided by the embodiment of the invention, the control plane anchor point and the user plane anchor point are separated, unified control coordination can be realized by adopting a structure of concentrating the control plane anchor point and dispersing the user plane anchor point, and meanwhile, as the user plane anchor point processes service data, load sharing and nearby shunting of service data flow can be realized, the bottleneck problem of data transmission can be avoided, and the data transmission delay is effectively reduced.

The foregoing describes a radio access network and a data processing scheme provided in the embodiment of the present invention, and the following describes a processing scheme of an IP packet provided in the embodiment of the present invention.

[ IP packet processing scheme ]

In the existing LTE system, service admission control is implemented by PCRF, PDN GW, MME, and other devices in the core network, involving a large number of network entities and a complex process. In the IP message processing scheme provided by the embodiment of the invention, the equipment in the wireless access network carries out service admission control, thereby simplifying the process of service admission control.

Further, the device in the radio access network may also perform Quality of Service (QoS) management on the IP packet, for example: and determining the empty port bearing for transmitting the IP message according to the QoS requirement of the IP message. The IP message processing scheme provided by the embodiment of the invention is not only suitable for processing the downlink IP message, namely the IP message sent to the terminal, but also suitable for processing the uplink IP message, namely the IP message from the terminal.

The IP packet processing scheme provided in the embodiment of the present invention may be implemented based on the network structure shown in fig. 3, and may be applicable to the network deployment scenarios shown in fig. 4B and fig. 4E, and the network function architecture may be as shown in fig. 7, fig. 5B, or fig. 5E. The implementation method comprises but is not limited to the following two optional implementation schemes:

alternative scheme one

Traffic admission control and/or QoS management is implemented by a third device in the radio access network, which may be the aforementioned control plane anchor 302.

Alternative scheme two

Traffic admission control and/or QoS management is implemented by a second device in the radio access network, which may be the user plane anchor 303 as described above.

The two alternatives described above are each explained in detail below.

Alternative scheme one

When the alternative is employed, the network functional architecture may be as shown in fig. 9. Compared with the network function architecture shown in fig. 7, the "joint RRM" of the third device further includes: traffic admission control and/or QoS management functions.

Alternative one is described below in conjunction with the specific process flow shown in fig. 10. It should be noted that the message names in the flow in the embodiment of the present invention are merely examples, and other names may be used as long as the implemented functions are not changed in the specific implementation.

The process shown in fig. 10 includes the following steps:

s1001: the terminal 33 initiates an RRC connection establishment procedure to the access node 301;

the terminal 33 initiates or autonomously initiates an RRC connection establishment procedure of a certain cell under the access node 301 under the instruction of the radio access network 30, so as to implement uplink and downlink synchronization with the cell under the access node 301, obtain C-RNTI, complete security-related signaling interaction, and bearer establishment and configuration procedures related to an air interface;

s1002: initiating a session establishment procedure between the terminal 33 and the first server 31;

the procedure may be initiated by the terminal 33, the first server 31 or even a third party. A Session Initiation Protocol (SIP) may be applied to establish a Session. SIP is a text-based application-layer control protocol for creating, modifying and releasing sessions for one or more participants, and can support and be applied to multimedia services such as voice, video, data, etc. The application layer signaling associated with the session establishment procedure is transported within the wireless communication system over the default bearer of the terminal 33 in a manner transparent to the wireless communication system.

S1003: the user plane anchor point 303 determines that the received IP packet has no corresponding air interface bearer;

such as: during or after the session establishment procedure in step S1002, the user plane anchor 303 finds that the IP packet cannot be mapped to the existing air interface bearer in the existing rule in the packet detection process of mapping the downlink IP packet to the corresponding air interface bearer.

Such as: the user plane anchor 303 may pre-store a corresponding relationship between a quintuple of the IP packet (i.e., a source IP address, a source port number, a destination IP address, a destination port number, and a transport layer protocol) and an air interface bearer, and when the user plane anchor 303 receives a downlink IP packet, determine, by detecting a value of the quintuple in the IP packet, which air interface bearer the IP packet should be mapped to for transmission, and transmit the IP packet to the terminal 33 through the corresponding air interface bearer.

Therefore, when the pre-stored correspondence between the quintuple of the IP packet and the air interface bearer does not include the quintuple of the received IP packet, the user plane anchor 303 determines that the IP packet does not have a corresponding air interface bearer.

S1004: the user plane anchor 303 sends a new service report to the control plane anchor 302;

after determining that the received IP packet has no corresponding air interface bearer, the user plane may send a new service report to the control plane anchor 302. Optionally, the IP packet or the five-tuple of the IP packet may be included in the new service report, so that the control plane anchor 302 determines the IP packet to be processed according to the IP packet or the five-tuple of the IP packet in the new service report. In addition, the new service report may further include a transaction identifier of the new service report to distinguish the new service report from other reports.

S1005: the control plane anchor 302 performs traffic admission control and/or QoS management;

optionally, the control plane anchor 302 determines an IP packet to be processed according to the received new service report, and the control plane anchor 302 obtains user subscription information of a user corresponding to the destination terminal of the IP packet, and determines to accept the IP packet when a service corresponding to the IP packet is a service allowed by the user subscription information; otherwise, determining to reject the IP message.

Such as: the control plane anchor 302 determines the destination terminal of the IP packet according to the destination IP address in the five-tuple of the IP packet in the new service report, and the control plane anchor 302 acquires the user subscription information of the user corresponding to the determined destination terminal. An optional implementation manner is that, during the process of accessing the terminal 33 to the wireless communication system, the second server 32 may send the user subscription information of the user corresponding to the terminal 33 to the control plane anchor 302 during the process of authenticating the user to the terminal 33, and the control plane anchor 302 stores the received user subscription information in the control plane anchor 302. The control plane anchor 302 determines the service corresponding to the IP packet according to the destination port number in the quintuple, and further determines whether the service corresponding to the IP packet is a service allowed by the user subscription information of the user corresponding to the destination terminal, if yes, it determines to admit the IP packet; otherwise, determining to reject the IP message.

If the control plane anchor 302 determines to reject the IP packet, a response message indicating that the IP packet is rejected is sent to the user plane anchor 303 through step S1010, such as: a new traffic handling indication. After receiving the new service processing instruction, the user plane anchor 303 discards the IP packet, and optionally, the user plane anchor 303 records a quintuple of the IP packet and discards a subsequently received IP packet with the recorded quintuple.

If the control plane anchor 302 determines to admit the IP packet, further, the control plane anchor 302 may determine a QoS requirement of a service corresponding to the IP packet, and determine an air interface bearer used for transmitting the IP packet according to the determined QoS requirement.

If it is determined that the air interface bearer to be used does not exist, or it is determined that the existing air interface bearer needs to be reconfigured, and the existing air interface bearer after reconfiguration is used to transmit the IP packet, for example: modifying the related parameters of the existing air interface bearer, such as: the guaranteed bit rate, etc. to support the service, step S1006 is performed.

S1006: the control plane anchor 302 initiates a bearer configuration procedure;

the control plane anchor 302 sends a bearer configuration message to the user plane anchor 303, where the message may also be regarded as a new service processing indication, the bearer configuration message may include a newly-created or reconfigured parameter of an air interface bearer, and the user plane anchor 303 configures, according to the received parameter, an air interface protocol stack (such as a PDCP layer) of a second part of the air interface bearer; the user plane anchor 303 sends a bearer configuration message to the access node 301, and instructs the access node 301 to configure the air interface protocol stack of the first part according to the parameters in the bearer configuration message.

Alternatively, the control plane anchor 302 may specify one or more access nodes 301 in a bearer configuration message, and the user plane anchor 303 sends the bearer configuration message to the specified performing access node 301.

Optionally, the control plane anchor 302 may also send bearer configuration messages to the user plane anchor 303 and the access node 301, respectively, to instruct the two devices to configure an air interface protocol stack, respectively. The bearer configuration may include: and the air interface bearing is increased, modified and deleted.

Optionally, the air interface protocol stack of the first part includes: a physical PHY layer, a media access control MAC layer and a radio link control RLC layer, wherein the air interface protocol stack of the second part comprises: a packet data convergence protocol PDCP layer; or

The air interface protocol stack of the first part comprises: a PHY layer and an MAC layer, the second part of the air interface protocol stack comprises: an RLC layer and a PDCP layer; or

The air interface protocol stack of the first part comprises: and the PHY layer, the second part of the air interface protocol stack comprises: a MAC layer, an RLC layer, and a PDCP layer.

S1007: after the air interface bearer configuration is completed, the access node 301 and the user plane anchor 303 send a bearer configuration completion message;

optionally, after the access node 301 completes bearer configuration, a bearer configuration completion message is sent to the user plane anchor 303, and the user plane anchor 303 further sends a bearer configuration completion message to the control plane anchor 302; or, after completing bearer configuration, the access node 301 and the user plane anchor 303 respectively send a bearer configuration completion message to the control plane anchor 302.

S1008: the control plane anchor 302 sends an RRC connection reconfiguration message to the terminal 33;

after receiving the bearer configuration completion message sent by the user plane anchor 303, the control plane anchor 302 determines that the radio access network 30 has completed configuration of an air interface bearer, and then sends an RRC connection reconfiguration message to the terminal 33 to initiate a configuration process of the air interface bearer at the terminal 33. The RRC connection reconfiguration message includes configuration parameters of an air interface bearer.

S1009: the terminal 33 sends an RRC connection reconfiguration complete message to the access node 301;

after the terminal 33 completes the configuration of the air interface bearer, it sends an RRC connection reconfiguration complete message to the control plane anchor 302.

S1010: the control plane anchor 302 sends a "new traffic handling indication" message to the user plane anchor 303.

The above-described steps S1006 to S1009 are optional steps. If the control plane anchor 302 rejects the IP packet in the service admission control process of step S1005, the control plane anchor 302 directly sends a new service processing indication message containing information indicating that the IP packet is rejected to the user plane anchor 303 through step S1010, such as: a "reject instruction" is included in the message.

If the control plane anchor 302 accepts the IP packet and does not need to perform configuration of air interface bearer, for example: the IP packet may be mapped to the existing air interface bearer for transmission, and the parameters of the existing air interface bearer do not need to be changed, the control plane anchor 302 also directly sends a new service processing indication message containing the identification information of the destination air interface bearer to the user plane anchor 303 through step S1010, so as to indicate the user plane anchor 303 to map the IP packet to the destination air interface bearer.

If the control plane anchor 302 accepts the IP packet and needs to perform the configuration of the air interface bearer, after step S1006 to step S1009, the control plane anchor 302 may send a new service processing indication message including the destination air interface bearer identification information and the destination air interface bearer QoS information to the user plane anchor 303. One possible implementation manner is that, for the terminal 33, there is only a default air interface bearer, and all the service data is transmitted on the default air interface bearer. In this case, the control plane anchor 302 may indicate "admission" or "rejection" only in the new service processing indication message without performing steps S1006 to S1009, and need not include the destination air interface bearer identification information nor the QoS information of the destination air interface bearer.

The new service handling indication message may contain a transaction identification to enable the user plane anchor 303 to identify which new service reporting handling indication is.

Alternative scheme two

The main difference between the second alternative and the first alternative is that in the second alternative, the traffic admission control and/or QoS management is performed by the user plane anchor 303 instead of the control plane anchor 302, optionally the user plane anchor 303 may obtain the required user subscription information from the control plane anchor 302.

When alternative two is employed, the network functional architecture may be as shown in FIG. 11. Compared with the network function architecture shown in fig. 7, the second device further includes: traffic admission control and/or QoS management functions.

Alternative two is described below in conjunction with the specific process flow shown in fig. 12. It should be noted that, the message names in the flow in the embodiment of the present invention are only examples, and other names may be used as long as the implemented functions are not changed in specific implementation.

The process shown in fig. 12 includes the following steps:

s1101 and S1102 are the same as step S1001 and step S1002 in alternative one, respectively;

s1103: the user plane anchor point 303 determines whether the quintuple of the received IP packet is an absent quintuple;

such as: during or after the session setup procedure of step S1102, the user plane anchor 303 may find a new IP packet whose five-tuple does not appear in the process of performing scheduling priority control on the downlink IP packet.

Such as: the user plane anchor 303 stores five tuples (i.e., source IP address, source port number, destination IP address, destination port number, and transport layer protocol) of the IP packet in advance, and when the user plane anchor 303 receives the downlink IP packet, determines whether the five tuples of the IP packet are in the pre-stored five tuples by detecting values of the five tuples in the IP packet, and if not, determines that the received five tuples of the IP packet do not appear.

If the user plane anchor 303 has the user subscription information of the user corresponding to the destination terminal of the IP packet, step S1106 is directly executed; otherwise, step S1104 is executed to request the user subscription information from the control plane anchor 302.

S1104: the user plane anchor 303 sends a user subscription information request message to the control plane anchor 302;

this step is only required when the user plane anchor 303 does not have the user subscription information of the user corresponding to the destination terminal of the IP packet. The request message may contain at least one of the following information for identifying the destination terminal of the IP packet:

the IP message;

a quintuple of the IP message;

the source IP address of the IP message;

the destination IP address of the IP message.

In addition, the request message may also contain a transaction identifier to distinguish the request message from other messages.

S1105: the control plane anchor 302 sends a user subscription information response message to the user plane anchor 303;

during the process of accessing the wireless communication system by the terminal 33, the second server 32 will send the user subscription information to the control plane anchor 302 during the process of authenticating the user of the terminal 33, and the control plane anchor 302 stores the received user subscription information.

The control plane anchor 302 determines the corresponding user subscription information according to the information for identifying the destination terminal of the IP packet, which is included in the request message, and sends the determined user subscription information to the user plane anchor 303 through a user subscription information response message.

Optionally, the user subscription information response message may contain a transaction identifier, so that the user plane anchor 303 determines to which user subscription information request message the response is.

Alternatively, the control plane anchor 302 may also actively send user subscription information to the user plane anchor 303, such as: after the change of the subscription information of the subscriber has occurred.

S1106: the user plane anchor point 303 performs service admission control;

the user plane anchor 303 may determine whether to admit the IP packet according to the received user subscription information. If the IP message is determined to be rejected, discarding the IP message and the subsequent IP message with the same quintuple as the IP message; if the admission is determined, QoS management is further performed on the IP message according to user subscription information and/or Differentiated Services Code Point (DSCP) information in an IP header. The QoS management method performed by the user plane anchor 303 may refer to the processing of the control plane anchor 302 in the first alternative, and will not be described herein.

Optionally, the user plane anchor 303 may determine, according to a destination port number in the quintuple of the IP packet, a service corresponding to the IP packet, and further determine whether the service corresponding to the IP packet is a service allowed by user subscription information of a user corresponding to the destination terminal, and if yes, determine to accept the IP packet; otherwise, determining to reject the IP message.

In the above, two alternatives of the IP packet processing scheme provided in the embodiment of the present invention are described. Service admission control and/or QoS management are/is realized through the user plane anchor point 303 or the control plane anchor point 302, so that the complex processing flow in the existing LTE system is avoided, and the realization is simple.

When the scheme is adopted for QoS management, the participation of core network entities such as PCRF, PDN GW and MME is not needed, and the complex process of identifying the service by the IMS system and the process of establishing the bearing for the service in the core network are also saved.

The first alternative and the second alternative of the wireless access network, the data processing scheme and the IP message processing scheme provided by the embodiment of the invention are introduced.
